If you find that your husband is having an affair, but he refuses to admit it, how can you make him admit it?

Dear friends recently found out that he was having an affair with a woman, and that woman sent a message. Dear, why didn't you call me for so long? Don't you love me? I can't get in touch with him if I want to, because he turns off his phone every day and learns that I have quarreled with him and says, [Dear, I'm sorry, I heard that you quarreled with your wife, right? The third sentence is [Dear, will you come back? I have a lot to say to you. Finally made a lot of phone calls. I answered a woman's voice. But I didn't scold her, and I didn't make any noise, because I felt boring. I was separated from him for a long time, and his cell phone was turned off when he came back. I believe he didn't check it until he said that he had downloaded a very good movie. I called at least seven or eight times in one morning. Dear friends, I am the mother of two children, both of whom were delivered by caesarean section. For the sake of the children, I didn't make any noise, but I'm not willing now. I want to write it for you to help me analyze whether they are related or not, because he refuses to admit it. Moreover, when I told the woman in front, the woman immediately argued that she didn't send a text message or call, saying that she did. 1? three
